Oil is something I learned a lot about today.  A lot of bikes run cat converters and the Mobil 1 has reduced zinc and phosphorus levels so it will not clog up the cats.  They had to do this along with the other manufacturers.  They have been working on other things like esthers to do the same jobs.  I was also told that zinc's only role was to carry other atoms with it like sulphur that did the work.  There are other ways to carry the sulphur.

It was also pointed out, the pile I ride and think is a race bike is in reality very mildly tuned when compared to just about everything else out there, and any oil that works in a Busa or BMW RR 1000, et al, is more than good enough for me.  Mobil 1 is approved for these bikes.

Basically, the new Mobil 1 is OK and there are all sorts of other oils like Brad Penn that will do the job.  My thinking needed to be adjusted.  I also learned the top grade Silkolene will do what I want and I can get it for a "racer" discount at much less cost than the Mobil 1.  "Cheap uber alles" is my motto so I will start using it.

Type "Dogs Driving New Zealand" into u-tube.  Its amazing.  They teach the mutts how to drive and they do a decent job.  There are racing applications for this.

The estimate came back for the cylinder head.  New guides and valves are needed and everything else looks OK.  The head was set up for a 790cc motor with 9.5 to 1 compression or an 865cc engine with 10.5 to 1 compression.  It was ported, the intake manifolds were matched to the carbs and the smog system was removed.  That is all.  This was a Stage I cylinder head and it worked with the OEM 790cc cams or the Triumph Performance #813 cams.  I should have used racing valve springs with the #813 cams.

This is what I ordered for the Stage II head.  It is suitable for the big bore kit with the #813 cams.  2mm larger intake valve seats with 2mm larger intake valves.  These valves are custom made from stainless steel.  New guides throughout with the ends ground to match the roofs of the ported head.  New exhaust valves.  All valves ground so their lengths will put me in the middle of the shim adjustment range.  New racing valve springs with titanium keepers and steel collets, shimmed to proper installed lengths, and a racing valve job.

Could have been the ultimate American V-Twin in its time.  It could still be built.  Anyone have a spare Indian without a motor and a spare Vincent motor without a frame?

Tom,
You can buy a new Vincent twin motor ready to run for about 18k GBP or $29k USD

It is possible to buy a new Vincent engine or have one made from newly made spare parts.  These engines also can be bought new:  BSA Gold Star and Matchless G80 from a company in the Netherlands, various JAP (John A. Prestwich) engines from a Cameron in the UK, and Norton Commando twins from England.  Single cylinder engine road racing is popular in the UK and these overhead cam engines are available new:  Norton Manx, Matchless G50, and the AJS7R, I think.

The new Norton company makes, or says they do, or did, complete Manx race bikes.  New gearboxes are also available for most of these and almost all can be shoehorned into a Norton featherbed frame.  New parts are available from all sorts of sources for these chassis.  A person with money and patience can build a new old bike.

This is something I keep track of, rather than all the other stuff I should pay attention to.

Last Sunday Rose, Werner, and me grabbed our umbrellas and took the train up to Seattle to see the International Motorcycle Show.  There were three new Hondas on display that attracted a lot of attention.  Two were 500cc parallel twins.  The other was this air cooled four.  Theses are the specs.

CB1100 (optional ABS), 1140cc DOHC air cooled inline four cylinder, 31.3 inch seat height, curb weight 540 lbs w/o ABS and 549 Lbs with it, Candy Red color.
